Bug 242241

Application: kmail (1.13.3)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-gcc44 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

-- Information about the crash:
I got a new email with a big attachment to my IMAP account. When I selected the message, it was shown in the Reading panel and the progress indicator in the status bar began to run. While it was running, I clicked the attachment to download it, and KMail crashed.

The crash can be reproduced every time.

 -- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
The current source language is "auto; currently asm".
